Odroid C2 crashes with Bad mode in Error handler detected on CPUx

On Linux-Next 20160812 Hardkernel Ordroid C2 crashes reproducably with
errors like those listed below.

Same happened with 4.9.0-rc6-next-20161124
(cf. https://lkml.org/lkml/2016/11/26/63)
and v4.9-rc8.

The errors occur only under heavy CPU load like
git checkout linux-next
or building the kernel.

Could someone, please, give me a hint how to analyze the problem.

Best regards

Heinrich Schuchardt
